To all 'zu/mm. it 'may concern.'

Be it known that I, EDWARD BnNJns'roRr, e citizen of Canada, end e resident of Fenwood, in the Province of Saskatchewan and Dominion of Canada, have invented n. new and Improved Antsliid-Chnin, of which the following is s full, clear, end exact description.

The present invention relates to new and useful improvements in enti-skid devices for the wheels of motor vehicles.

The invention has for its primary object to provide a, device which may be used with all ty es oi' wheels with equal facility.

A urther object of the invention is to provide :i device of this character in which the tire issnbjected to s minimum amount of weer.

still further object of the invention is to provide e device of this character in which the severnl pnrts will readily clear themselves of mud :rnd the like.

Referring to the drnwings- V Figure l is a. sectional view of a, pneumatic tire showing the device thereon;

F'g. 2 is n plan view of a. portion of the device.

In the drawings, the reference character' 5 designates a tire which in the present instance is shown as of the pneumatic type.

Adapted to be positioned :it regu arly spnced intervals about `the tire on .its treed portion, ure relatively flat plates 6, pend, es best shown in Fig. 1, seid plates have their side edges nptnrned ns indicated nt 7. The

plates 6 are provided on their tread surface with n plurnlity of studs or rojectmo' members 8, which nre forme integrn'l therewith und are arranged in spaced reletion to euch other in rectnn iler form. Each of ihe plates 6 is provider on its side edges with spaced openings or apertures 9, the purpose of which will be heremafter described.

The reference character 10 designates continuous side chains, and connected to `scid side chains 10, :md extending radially Yontn'ardly over the plates 6, are short len ths of chain '1.1, there being two of these siert lengths of chain connected toeech side chain 10 edjuceut each of the plates 6. These short lengths of chain 11 have their inner or meeting ends secured together centrally of their respective plates 6, by means of a single link 12, seid link l2 being formed of n sinvfle length of suitable materiel with four su stnntioll circuler eyes 13 ywith which 'the end l of the short lengths of chain l1 are adapted to engage. In eddition to having their inner ends secured together hy the links 12, the short lengths of chain are each connected to the plates 6 by having one of their links, such es 14, passed through its respective opening 9 heretofore mentioned.

By this arrangement, it will be apparent that the lugs or projections 8 will serve to prevent skiddinor of the tire in e sidewise direction, sind tint owing to the fact that the short lengths of chain pass between said lugs, the possibility of said lugs clogging with mud 1s removed.

Havin thus described the invention, what is clnime is 1. A device of the character described comprisin n pair of side chains, n. plurality of trend p etes provided on their treed surfece with integral projections, and chains carried by scid1 side chains and being connected together centrally of said plates, seid of said trend plates.

2. An enti-skid device for tires comprising n pair of side chains, a plurality of trend plates, integral lugs projecting from said trend plates, chains connecting the side chains and extending across the tread of the tire and trend plates and lying between the integral lugs of said trend plates, and means for connecting seid cross chains centrally of the tread plates.

3. A device of the character described comprising n Jair of continuous side chains, e plurality oi tread plates having integral projections on their tread surface, n pln rnlity of chains carried by said side chains and overlying seid tread plates between the integml lugs thereof, and means centrally of seid trend plates for connecting the ndjncent ends of seid chains.

4. An enti-skid device comprising n plurality oi side chains, n. plurality of trend plates, and n plurality of cross chains for each of seid trend lates, said cross chains being secured to seid treed plates neer their edges and to each other, substantially cenalntes.
